2.Display: 2416 supports 2D image acceleration and the maximum resolution is 1024x768. At the same time, 2416 has bitbltThe two-layer pixel display function is similar to the two-layer pixel display function. In terms of pixel display and capturing, there is no big difference between independent 2D graphics acceleration graphics, such as sm502. While 2440 does not accelerate 2D images, it can only support up to 800x480 (not blinking). Therefore, in terms of display, 2440 has many defects and m

If there are a lot of errors during the loading of WCF, it is basically a reference problem. It is better to let vs generate a reference list by itself. So first add a Silverlight enabled WCF -- call temp, and then delete it, And the ref will be done well.
From to 10, the WCF can be properly generated, but it cannot be used. A Not Found error

When the system restarts, imx51 samples the Startup Mode gpio pins (boot_mode [1:0]) and stores the sampled values in the sbmr register (system reset controller Boot Mode register ). The startup modes supported by imx51 include: Internal startup mode (start peripherals are determined by gpio pins in startup mode), test mode, and download mode (download code through USB/UART) and internal startup mode (determine the startup peripherals by fuse bit in startup mode ).

The idea of a hybrid hard drive is similar to the "Ready Boost" feature on Microsoft's new generation of Windows Vista and Windows 7 operating systems, both by increasing the speed of flash memory for Data prefetching (Prefetch) to reduce the number of reads from the hard disk and thus improve performance. The difference is that a hybrid hard drive integrates the Flash memory module directly onto the hard drive, comparing it with a new generati

The internal parts of the mechanical hard disk are more complex than the solid-state hard disk, there are no motors and fans inside the solid-state hard disk, so in this aspect the solid-state drive will have a great advantage over the mechanical hard disk, while the solid-state hard disk is much quieter than the mechanical hard disk in the work. In addition to the power consumption, solid-state hard drives are also lower than the traditional mechanical hard disk.
